Abstract
A system for producing parameters for a bass-enhanced loudspeaker enclosure; meanwhile, a low-frequency extended frequency, a quality and quantity ratio and radius of a port need to be defined for the system. Also, the resonance frequency of a mechanical system and the quality and quantity of a mechanical system are fixed to obtain the parameters for the frequency ratio, the length of the duct and the cavity volume inside the device, etc. and to manufacture the bass-enhanced loudspeaker enclosure.
